Abstract
A backside illuminated image sensor has a carbon nanotube transparent conductive coating formed on the backside of the image sensor. In one implementation the carbon nanotube transparent conductive coating acts as a wavelength selective filter to filter out infrared light. In one implementation the carbon nanotube transparent conductive coating has an optical transparency between 50% and 80% for blue and green color bands.
